What will fit in a 2.5 inch hole?

In 1960 previous owner had a 2.5 inch hole drilled 200 feet with water at about 160 feet. I have checked this with a steel tape. He had installed a Jet Pump, which was removed when County water arrived. I would like to obtain water from the well for irrigation and a pond. Should I.
Buy a new Jet pump $300
Buy and install a rod/sucker pump $2200
Drill a 4 inch well and use a submersible. $5000-$6000

Forget the two point five inch well. You will never find a 2.5' packer or casing adaptor. They are totally obsolete. A deep well jet won't work at 165 feet anyway.

Go for the new system and a four inch submersible.

A 4 inch hole is the way I have been leaning. I understand a submersible is more efficient at 160 feet. Since the previous owner had a red jacket single line jet pump working at this depth ~$800 I suspect another jet pump might work. However, I have been told a rod pump would work on a 2.5 inch well. Is a rod pump more or less efficient. Since I have to remove all the jet pump plumbing, I may still be back to a 4 inch hole. The rod pump just left me thinking again about a cheaper alternative.

This is only for a garden and pond both small ~3/4 acre.

Speedbump, would a windmill work that deep?

You could use the wind mill to pump water out of the ground into the pond, then use a jet pump to suck water out of the pond for irrigation purposes.

There are submersible pumps that will fit in a two-inch pipe, but they are used by the water monitoring trade, and don't put out much water or pressure.

Is the old packer still in that 2.5" pipe, so that a convertible jet pump could be connected to it?

I think a rod pump would work at that depth, and even much deeper.

A rod pump will work if you have enough horse power to lift it, the problem would be finding a 2.5" plunger. I don't think you can find one anywhere these days unless you find an old driller who has an old one hanging around. The pump companies quit making 2.5" stuff years ago.

Bob, since you don't carry this stuff, I hope I can pipe (pun intended) in here.

Try, these guys:

Thanks Rancher,

I knew there was someone making smaller Eureka Cylinders than the norm, but they still are very hard to get down a 2" well. Due to the age of the well, the build up of minerals and the length of the cylinder, the pipe has to be very straight.

What I said was it would be impossible to find a deep well jet or casing adaptor for a 2.5" well or a plunger for the same. I don't think I mentioned cylinders because I do sell them.
